Turn the BHT on, bring the bar-code reading window to the bar code to be scanned, 
and press the trigger switch. The BHT turns on the illumination LED to scan the bar 
code. 

When the BHT has read the bar code successfully, the indicator LED will illuminate 
in green. 

   

 

• If the BHT fails to read due to specular effects 

or other factors, change the scanning angle of 
the reading window or the distance from codes 
as shown at right, and try it again. (Specular 
effects occur when the reflection of the light 
from the bar code becomes excessively strong. 
This can easily happen when the reflecting 
surface is polished or covered with vinyl.) 

•  To read bar codes wider than the readable area 

of the bar-code reading window, pull the 
bar-code reading window away from bar codes. 
The BHT can read bar codes at a maximum 
distance of 45 cm (17.7") from the bar-code 
reading window, respectively. **

so follow the application’s manual.
